$derivdef\left(-5+8-5\right)$
Learn how to solve definition of derivative problems step by step online. Find the derivative of -3+8+-2+-5 using the definition. Subtract the values -3 and -2. Subtract the values -5 and -5. Subtract the values 8 and -10. Find the derivative of -2 using the definition. Apply the definition of the derivative: \displaystyle f'(x)=\lim_{h\to0}\frac{f(x+h)-f(x)}{h}. The function f(x) is the function we want to differentiate, which is -2. Substituting f(x+h) and f(x) on the limit, we get.
